Jacquard Acid Dyes are premixed colours for protein fibres such as silk, wool, angora, cashmere, feathers and most nylons. These fabric dyes can be applied in a dye bath, sprayed, painted with, or used for printing when combined with a thickener such as Manutex. They are fixed by combining hot water and 1 heaped tablespoon of citric acid to each 500g of dry fibre weight or 4 table spoons of vinegar.
Six colours are now identified by Jacquard as Neon / Fluorescent – see 
on colour chart. “These are the most electric and vibrant colours possible for silk, wool and nylon. The Blacklight Blue is especially unique: the colour is pale and subdued under normal light, but glows brightly under blacklight.” Please note that Chartreuse and Hot Fuchsia may still have different labels from those shown in the photograph until replaced by Jacquard.
Each 14g pot of Jacquard Acid dye will dye just under 1kg dry fibre, depending on the intensity of colour required, and instructions are included on the pot.
Jacquard have produced comprehensive usage instructions for Jacquard Acid Dyes (opens in a new window). It includes information for using Acid dyes for Silk Painting, in the washing machine, Screen and Hand Printing, and Immersion dyeing. These useful instructions will also apply to the Fibrecrafts range of Acid dyes.
Alternative: Fibrecrafts Acid dyes are available in larger quantities and in a smaller colour range, although with measured mixing, most colours can be achieved.
